Was Israel’s covenant really just to benefit the Gentiles?

Paul himself marveled at how God could use Israel’s disobedience to their covenant as opportunity to bring salvation to the Gentiles:

Rom. 11:11  I say then, they did not stumble so as to fall, did they? May it never be! But by their transgression salvation has come to the Gentiles, to make them jealous.
Rom. 11:12 Now if their transgression is riches for the world and their failure is riches for the Gentiles, how much more will their fulfillment be!
…
Rom. 11:30 For just as you once were disobedient to God, but now have been shown mercy because of their disobedience,
Rom. 11:31 so these also now have been disobedient, that because of the mercy shown to you they also may now be shown mercy.
Rom. 11:32 For God has shut up all in disobedience so that He may show mercy to all.
Rom. 11:33  Oh, the depth of the riches both of the wisdom and knowledge of God! How unsearchable are His judgments and unfathomable His ways!
Rom. 11:34 For WHO HAS KNOWN THE MIND OF THE LORD, OR WHO BECAME HIS COUNSELOR?
Rom. 11:35 Or WHO HAS FIRST GIVEN TO HIM THAT IT MIGHT BE PAID BACK TO HIM AGAIN?
Rom. 11:36 For from Him and through Him and to Him are all things. To Him be the glory forever. Amen.
